    Abstract: The present invention relates to a peptide capable of binding to rheumatoid arthritis autoantibodies, which is a consecutive 10-25 amino acid sequence of any one fragment of the group consisting of SEQ ID NO: 3-4, 7-13 or 16-19, wherein the peptide fragment has an epitope that binds to the rheumatoid arthritis autoantibodies. Furthermore, the peptide fragment bound to the rheumatoid arthritis autoantibodies is used for testing rheumatoid arthritis, and according to this use, the present invention provides a method for testing rheumatoid arthritis disease and a test reagent kit used for determining whether a subject to be tested suffers from rheumatoid arthritis disease.

    Abstract: Methods and device for quantification of an analyte in a sample are provided. An example has the following steps: the sample is introduced into at least one test split channel (306). The test split channel (306) comprises a test reaction portion (306a). The analyte (410) in the sample is to bind to capture reagents (408) provided in the reaction portion. Analyte (410) bound to the capture reagents (408) is contacted with a reactant solution. The reactant solution comprises a plurality of reagent coated microparticles (412) for binding with the analyte (410). Residual reactant solution comprising unbound microparticles is received. The residual reactant solution is analyzed to quantify the analyte.

    Abstract: The present invention provides an improved method of quantitative and/or qualitative analysis of a target molecule using nitrocellulose membrane (NCM). In particular, the present invention provides a porous nitrocellulose membrane that includes a surface and an organic nanostructured molecule that is non-covalently attached to the surface of NCM. The organic nanostructured molecule has a branched region that includes a plurality of terminal region (e.g., terminal end) moieties that are non-covalently attached or bound to a surface of the porous NCM. The organic nanostructured molecule also comprises a linear region that includes a covalently attached capture molecule that is adapted to selectively bind to a target molecule. The NCM of the invention provides an improved reproducibility, reliability, and selectivity compared an NCM in the absence of the organic nanostructured molecule.
